A 61-year-old Waterport man was arrested Monday on second-degree murder charges in the death of a woman whose body was found on a road not far from the house they shared, the Orleans County Sheriff’s Office said.

Frederick C. Miller was charged with killing Rachel A. Miller, 53, whose body was found along Oak Orchard River Road in the Town of Carlton, about 150 yards from the house they shared, at about 7 a.m. by a passing school bus driver. The driver called 911.

Officials said the suspect and the victim were not married and were not siblings but would say no more about the fact that they had the same last name.

Sheriff Scott D. Hess and Undersheriff Steven D. Smith said an investigation confirmed there was some kind of physical altercation between the victim and suspect inside the home. That altercation apparently continued outside the house and down the road, where she was left dead.

The undersheriff said the victim’s body has been taken to the Monroe County Medical Examiner’s Office in Rochester for an autopsy to get an official cause of death. He confirmed that she suffered a blunt-force injury that may have killed her.

Frederick Miller was remanded to the county jail following arraignment in Carlton Town Court on Monday. The investigation by the Sheriff’s Office and the State Police Forensic Identification Unit is continuing, Hess said.
